The platform will not support atomic compare-and-set operations.

• How do I accurately handle a batch separator for SQL from C#

  - by Sam Saffron

  For Data Explorer I would like to add support for a Batch separator. So for example if users type in: select 'GO' go select 1 as go Go select 100 I would like to return the three result sets. Its clear that I need some sort of parser here, my hope is that this is a solved problem and I can just plug it in. (writing a full T-SQL parser is not something I would like to do) What component / demo code could achieve splitting this batch into its 3 parts?

  - by Misha Moroshko

  I would like to develop a site using jQuery that will work with all major browsers. I thought to start with a basic layout (a header, a couple of tabs with content, and footer). I wonder how should I create this layout to support different screen resolution, screen size, or window size. Should I work in pixels / points / percents when defining width and height of the components ? Are there any jQuery plugins that can help me with this task ? Thanks !

• Which computer assisted translation format should I use for a ColdFusion site?

  - by user284950

  I am creating a multilingual site that will need to support at minimum five different languages, including Korean and Chinese. The site language is ColdFusion, so Java is the native language. I want to make the site as easy as possible for the next programmer to update, and for third-party translators to use tools that will work easier for them than digging through a SQL database. So far I have come across Resource Bundles, GNU's GetText, and TMX. Which do you recommend and why?

The software should support running from the command line so that virus scan be included into the build process. Edit: I understand that prevention techniques work better than any antivirus, but the employer demands that commercial AV software be used in the development environment (looking a replacement for horrible Symantec Antivirus).
